A just and global solution to the problems of international taxation is required if developing countries are to realise economic self-sufficiency. But if developing countries cannot have a meaningful voice in global tax rules, then they have every justification for going their own way.

As Mr Gardner enters his second year as US Ambassador to the EU I hope he will reconsider his views on this controversial issue and use his influence positively to encourage companies to act in the wider interests of society as a whole by moving away from aggressive tax avoidance.

The inevitable question that will arise in the right wing press will, however, be about whether this will result in three things. The first is an exodus of wealthy non-doms. The second is a collapse in London house prices as a result. And the third is a collapse in tax revenues. Let me deal with these issues...

Dealing with the current problem is not rocket science, but it needs the political will to be there to take action. Fortunately one Party has that political will: Ukip.
